Yes. Instagram’s explanation was they thought the account was an impersonator of Andrés Iniesta and disabled it/gave it away.
Usually if Instagram wants your account they add underscores to the original handle like they did with @sussexroyal.
And this is why I’ll never use Facebook or Instagram again. I can’t even begin to imagine and angst the OP is going through right now. Imagine if it was your business? My sister uses Instagram exclusively to market and promote her beauty salon business. I can only imagine what her reaction would be if something like this happened to her (really my only reference). Letting people have access to data let’s people manipulate that data. Whether this was an insider giving his friend the account or it was hacked and taken over, it doesn’t matter how, things like the OP’s situation should NEVER exist.
